Here is one suggestion.

You may need to replace the PRAM battery. It is a 3 volt, lithium CR2032 watch/camera battery available at stores like Walmart, Kmart, Target, or most drugstore chains. You should be able to the replacement yourself on any G5 iMac EXCEPT the iSight models.

Here's a link to the PRAM battery:
